I'm gonna be building a box for my 15" Incriminator LI later today, and I used the RE Box calculator to help with some dimensions... I know that thing's not reliable in some cases, can someone with bbp or something like that run a quick check for me?

My dimensions are:

Width: 32
Height: 12
Depth: 25
Port: 19"
Port width: 5
3.574 cu ft

Hopefully, as RE says, that tunes to around 35 hz.. But like I said, I've heard it's unreliable and want a quick check if someone could do that.
